I had one before I bought the latest two and find it interesting that all three were made in Switzerland.
...nice!...from the lettering, those look like US-made day and date discs in there (the Swiss-made discs have a definitely different style of lettering)...perhaps Swiss-built with a US 2182 movement (rather than the Swiss 2182F)?...
...edit: oh...wait...that second crown was throwing me off and making me wonder if that has a totally different or modified movement in it...
...then I realized the extra crown is just for rotating the ring inside the case and is not part of the movement...d'OH...
...yes, folks, I am NOT an Accutron expert...:blushing:...but I HAVE succeeded in resurrecting my 'Sputnik'!!...
